This record is for the highest capacity times distance product over a commercially operated fibre-optic link.
This record is measured in Tb/s.km and in multiples thereof.
For the purposes of the record, the capacity-distance product is defined as the number resulting from multiplying the link's capacity in Terabits-per-second with its length in kilometres.
For the purposes of the record, a commercially operated fibre-optic link is defined as optical data cables which carry commercial network traffic.
